How can I reliably identify a specific error in PHP?

Question

Because of PHP\'s unlink() not supporting exceptions natively, I\'m making a wrapper function for it. It should throw a FileNotFoundException if, w

I would simplify the code:

public function deleteFile($path){

    if (!file_exists($path) {
        throw new FileNotFoundException();
    }else{
        unlink($path);
    }

    if (file_exists($path) {
        throw new FileNotDeleted();
    }
}

Then you don't have to catch the $errstr and do complicated error catching. And it will work down to PHP 4 when exceptions were introduced.
